Note:

      Earnings per common share was computed by dividing net income, increased
(decreased) for adjustments arising from minority interest in consolidated
subsidiaries, reduced by preferred stock dividend requirements, by the weighted
average of the number of shares of common stock and common stock equivalents,
where dilutive, outstanding during each period.

      Earnings per common share, assuming full dilution, was computed on the
assumption that all convertible debentures, convertible preferred stock, and
stock options converted or exercised during each period, or outstanding at the
end of each period were converted at the beginning of each period or at the date
of issuance or grant, if dilutive. This computation provides for the elimination
of related convertible debenture interest and preferred dividends.
